    Default how to connect 2 java files

    hi, i'm new to java and im using netbeans. i'm wondering if there's a way for 2 java files let's say A and B. using netbeam's ui editor i made 3 jbuttons on A and a textfield on B, i can make B appear once i click any of the buttons on A but what i wanted to do was make the textfield change value depending on which of the 3 buttons were pressed.

    any help is appreciated, thank you

    You have your main class (C) which contains an instance of JFrame, an instance of A and an instance B. I suppose A implements ActionListener to register the button events. Either you let C implement the ActionListener and on the events you take your B reference and set the text, or you pass the B reference to the A reference and set the text in there.

    actually the scope of what im doing is bigger but my example is sort of the jist, anyway the reason im using netbeans ui editor is so i can present what it's gona look like.


    under the action listener from A (the one with buttons) i made an instance of B and i tried doing the B.jTextfield.setText...

    but netbeans doesnt show the auto suggest while im typing B.(variables should be auto suggested after typing "B." right?) i've done smethng like this before i just can't figure out why i can't do it now

    thnks for the fast reply

    Well B is the class, you need the exact reference that is used in your JFrame, not any reference to B. So as I've already suggested, pass the b reference into your a refernce and use it there.
